摘要
在计算机联锁中输入输出数据处理的安全性是整个信号系统的关键,传统采用硬件电路进行采集和驱动,灵活性差,成本高,安全性低。鉴于此提出了基于安全编码的数据采集控制思路,使该安全处理子系统在自主研发的安全计算机平台上实现,具有成本低、扩展性好、配置灵活、安全性高等特点。
In computer interlocking, the safety of input and output data processing is critical to the whole signal system. Traditionally, hardware circuit is used for data acquisition and drive, which is poor in flexibility, costly and low in security. Thus, a safety coding-based design of data acquisition is put forward and realized over a domestically developed safety computer, featuring low cost, good expansibility, flexible configuration and high security.
